Sea levels worldwide rose an average of nearly 3 inches (8 cm) since 1992, the result of warming waters and melting ice, a panel of NASA scientists said on Wednesday.

In 2013, a United Nations panel predicted sea levels would rise from 1 to 3 feet (0.3 to 0.9 meters) by the end of the century. The new research shows that sea level rise most likely will be at the high end of that range, said University of Colorado geophysicist Steve Nerem.

Scientists and volunteers who have spent the last month gathering data on how much plastic garbage is floating in the Pacific Ocean returned to San Francisco on Sunday and said most of the trash they found is in medium to large-sized pieces, as opposed to tiny ones.

Volunteer crews on 30 boats have been measuring the size and mapping the location of tons of plastic waste floating between the west coast and Hawaii that according to some estimates covers an area twice the size of Texas.

In the Mississippi River town of Hannibal, Missouri, time apparently flies.

In 2013, Hannibal had a 50-year flood, a high-water event only expected once every 50 years. In 2014, it had another 50-year flood. Somehow, the river has reached its 10-year flood stage in Hannibal—which should happen about once a decade—in seven of the last eight years. And if the years seem to be passing with unusual speed, so do the centuries. Hannibal had a 200-year flood in 2008, considerably less than 200 years after an even larger deluge in 1993.

Evidence is mounting that Hannibal’s statistical anomalies have been caused not by glitches in the space-time continuum, but by a combination of floods getting worse and government estimates of flood risks being wrong.

This past Saturday, marked a notable 10th anniversary. But it was certainly nothing to celebrate. Ten years ago, President George W. Bush signed the Energy Policy Act of 2005. The giant energy bill included massive giveaways for the fossil fuel, nuclear and ethanol industries and provided only token incentives for renewables and improved energy efficiency.

But the most infamous piece of the law was what is now commonly known as the “Halliburton Loophole,” an egregious regulatory exemption that ushered in the disastrous era of widespread oil and gas fracking that currently grips our nation.

The federal government on Monday gave Royal Dutch Shell the final permit it needs to drill for oil in the Arctic Ocean off Alaska’s northwest coast for the first time in more than two decades.

The Bureau of Safety and Environmental Enforcement announced that it approved the permit to drill below the ocean floor after the oil giant brought in a required piece of equipment to stop a possible well blowout.
